  Meh. What I want is a HEDT CPU with only P-cores, and AVX-512 re-enabled as a result. Perhaps Sapphire Rapids will deliver that.

  Fishhawk Falls, Q4 launch maybe.

  HEDT is dead.
  
  Intel won't release an X299 successor. Their new Sapphire Rapids based HEDT is W, Workstation class. Meaning Prosumer just like Threadripper Pro. So expect a super high premium asking price.
  
  Gaming and Mobile industry killed HEDT. Nowadays most of them spend more time on their junk Smartphone consuming all the stupid Social media drama and etc. So PC users are only relegated to those so called "Gaming" which is mostly - Fortnite, Pubg, COD Warzone, Apex Legends. All this garbage. Not SP games. And Windows 11 direction is also more geared towards mobile UI.
  
  All in all HEDT is essentially gone.

  I disagree, as I think the core count wars killed HEDT.
  
  No game I know of (other than one beta MMO) can fully saturate a top end consumer CPU these days. And most workloads will get done *reasonably* quickly on a 12900KS or 5950X.
  
  You need more? Well thats what the P/W series is for. There's a lot of fixed-cost overhead designing something like X299 or TR4, and I don't think the volume justifies it over just making some workstationy motherboards/CPUs on a heavily amortized server socket.

  My old 3930K from over 10 years ago is still playing the latest and greatest games just fine. Overclocks like a champ too.
  Running Ryzen 9 at the moment with 64GB of Ram.
  
  But Quad Channel+6 Core/12 threads is what gave it that longevity because it's a HEDT platform.
  
  Fast forward to today... They essentially just moved HEDT chips onto consumer platforms and dialed up the core counts... Which is why the price points of high-end Ryzen 9 can align itself to older HEDT chip price brackets of old.
  
  There just isn't a dedicated socket for it anymore... Or Quad channel memory.

  I don’t think it’s possible to make a CPU faster anymore until Intel gets to 4nm; it just takes too much power.
  
  So their only choice is wider and more cores. Apple is a node ahead and will probably hit 3nm next year when Intel hits 4nm.

  Keep in mind that nodes are not directly comparable based upon pure marketing nomenclature.
  
  Intel 7nm for example is absolutely superior to TSMC or Samsung 7nm in actual feature sizes.

• michael2k - Sunday, July 31, 2022 - link

  Yes you are correct but also irrelevant. Intel 7 may be superior to TSMC 7 but inferior to TSMC 5 or TSMC 5P

• Zoolook - Monday, August 1, 2022 - link

  I guess you mean Intel 7, which is their renamed 10nm, and it's debatable, Intel 7 never reached their initial proposed logical density and in comparisons of chips they seem to have less than 10% lead in density and their volume production launched years after TSMC and it's clearly worse in power efficiency.
  TSMC is gearing up volume production on N3 which is a year ahead of Intels comparable (projected density) Intel 4 process.

  It’s funny how Apple still has a ‘jest’ CPU; 16 pcores and 4 ecores in the M1 Ultra.
  
  But AMD still sells a 16 core part too:

  https://www.amd.com/en/products/cpu/amd-ryzen-9-59...
  
  The real question is if core counts will go up with the M2 Ultra; adding 2 p cores to the M2 Max (10/2) would give the M2 Ultra 20/4
  
  The problem Intel and AMD have is that their power draw is so high it gets hard to add more cores and still cool the part.
